Personal projects
Resident Evil Outbreak: File #2 sourceless port
STATUS: Work in Progress
Attempting to completely reimplement the entire game in C++ via reverse engineering the original game's code in Ghidra while adding additional quality of life improvements like support for higher resolutions, scalable UI, and higher framerates. Code is written in a way that it would require the potential player only to copy a couple of files from their legitimate copy of the game.
I also try sometimes to write about the internals of the game, mostly descriptions of used file formats and whatnot, which can be used as a reference when modding the game.
What's done?
- correct rendering of stages, characters, objects;
- animation playback;
- stage collision;
- cutscene playback;
- basic player movement, interaction with the environment, able to partially progress through the scenarios;
- custom audio mixing with authentic PS2 reverb, playback of character and room sounds, playback of original ADX streams (music and character ad-lib voicelines);
- partial inventory implementation;
- ...and many more things that I couldn't get from the top of my head. :)
What needs to be done?
- NPCs, Enemies;
- Enemy AI, NPC AI;
- hit detection for combat;
- player combat states;
- scenario specific task code;
- the entirety of netcode;
- ...and much, much more.

Megami Ibunroku: Persona (PS1) English translation
STATUS: Work in Progress
Script is being translated by Tom. A lot of work done making sure the game displays English text nicely, and much more has to be done in the future.

Shin Megami Tensei (PS1) English translation
STATUS: Complete
Completely translated Japanese script by Tom. I've worked on the ROM Hacking: added support for a variable width font, rewrote parts of the game's code to correctly work with ASCII text instead of the game's original 2-byte encoding, fixed menus to fit the final English text, etc...
